Massively annoying.

The telling thing is that its happened at the weekend. If it were someone with a grudge its more likely to happen any night of the week. Probably someone whose had a few sherbets and on the way home. Is there are convenience store nearby? Often these useless pieces of skin buy eggs to use just beforehand. Ask the shop keeper if they've had repeated late night purchases of eggs.
An IP camera that sends images and/or video to a networked drive and/or emails them. I've had one overlooking the cars on the drive for quite a few years. You can set the sensitivity so it only triggers on movement in certain parts of the image. However, because its on the street theres likely to be lots of movement.
A bit more expensive - a GoPro with a massive memory card and external battery pack to sit tucked away in the car recording constantly (switch the LEDs off). Or, a sleepless night just sat there watching.
Alternatively, time for a Dakar respray
